Prior to 22.0.0-rc.2, 21.2.15 20.3.22, and 19.2.23, an issue in the @angular/service-worker package compromises the integrity of request-policy enforcement during request reconstruction. When the Angular Service Worker intercepts network requests for matched assets, it reconstructs a new Request object using an internal helper function. During this reconstruction process, the helper function strips the strict, client-defined request redirect policy configuration (such as redirect: 'error'), falling back to the browser's default 'follow' strategy. If the target web application makes client-side requests with a strict policy (e.g., expecting a network error instead of automatically following redirects), the service worker will bypass this instruction and automatically follow HTTP 3xx redirects to other destinations. This acts as an unintended proxy/intermediary (\"Confused Deputy\") and can result in cookie/credential exposure or same-origin session-restricted data leakage if public dynamic routes redirect to sensitive routes. This vulnerability is fixed in 22.0.0-rc.2, 21.2.15, 20.3.22, and 19.2.23.","published_at":"2026-06-22T15:41:17.125000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":5.7,"cvss_v4_vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","cvss_v4_severity":"MEDIUM","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-200","CWE-441","CWE-524"],"nvd_references":["https://github.com/angular/angular/security/advisories/GHSA-gv2q-mqqv-365m","https://github.com/angular/angular/pull/67494"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:47.205953Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"H","value_label":"High"},{"metric":"AT","name":"Attack Requirements","value":"P","value_label":"Present"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"P","value_label":"Passive"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"N","value_label":"None"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"N","value_label":"None"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"angular","vendor_name":"angular","product_slug":"angular","product_name":"angular","version_start":">= 22.0.0-next.0, < 22.0.0-rc.2","version_start_inclusive":true,"version_end":">= 22.0.0-next.0, < 22.0.0-rc.2","version_end_inclusive":true,"cpe23_uri":"cve5:angular:angular:>= 22.0.0-next.0, < 22.0.0-rc.2:>= 22.0.0-next.0, < 22.0.0-rc.2"},{"vendor_slug":"angular","vendor_name":"angular","product_slug":"angular","product_name":"angular","version_start":">= 21.0.0-next.0, < 21.2.15","version_start_inclusive":true,"version_end":">= 21.0.0-next.0, < 21.2.15","version_end_inclusive":true,"cpe23_uri":"cve5:angular:angular:>= 21.0.0-next.0, < 21.2.15:>= 21.0.0-next.0, < 21.2.15"},{"vendor_slug":"angular","vendor_name":"angular","product_slug":"angular","product_name":"angular","version_start":">= 20.0.0-next.0, < 20.3.22","version_start_inclusive":true,"version_end":">= 20.0.0-next.0, < 20.3.22","version_end_inclusive":true,"cpe23_uri":"cve5:angular:angular:>= 20.0.0-next.0, < 20.3.22:>= 20.0.0-next.0, < 20.3.22"},{"vendor_slug":"angular","vendor_name":"angular","product_slug":"angular","product_name":"angular","version_start":">= 19.0.0-next.0, < 19.2.23","version_start_inclusive":true,"version_end":">= 19.0.0-next.0, < 19.2.23","version_end_inclusive":true,"cpe23_uri":"cve5:angular:angular:>= 19.0.0-next.0, < 19.2.23:>= 19.0.0-next.0, < 19.2.23"},{"vendor_slug":"angular","vendor_name":"angular","product_slug":"angular","product_name":"angular","version_start":"<= 18.2.14","version_start_inclusive":true,"version_end":"<= 18.2.14","version_end_inclusive":true,"cpe23_uri":"cve5:angular:angular:<= 18.2.14:<= 18.2.14"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/angular/angular/security/advisories/GHSA-gv2q-mqqv-365m","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/angular/angular/pull/67494","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-22T15:41:17.125000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:55:22.518073Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:22.518073Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:22.518073Z","label":"CVSS score revised","source":"cvelistv5"}]}
